Consider a macroscopic system of two blocks that are in thermal contact. The two-block system is isolated from the rest of the universe. Initially, a hotter block is at a temperature TH and a colder block is at a temperature TC. In the final state of the system, the two blocks are at the same intermediate temperature TI.
A. Compare the following quantities for the initial state and final state: Entropy for the block that starts at TH
Sf > Si Sf < Si Si = Sf not enough information
Entropy for the block that starts at TL
Sf > Si Sf < Si Si = Sf not enough information
Combined entropy for the two block system
Sf > Si Sf < Si Si = Sf not enough information
B. Consider the following statement: "When the blocks approach equilibrium, they move to a final state that is more natural, so their level of order increases.
"Do you agree with this statement?
Does this statement agree with the second law of thermodynamics?
